I think what devs usually mean by maxing out the machines is that at that moment the game was done there exepriance and know how was maxed out on the machine. Next time they work on a title they might find new ways of making things work and have a better understanding of the machine as well as there own tech meaning may the next game will max out the machine and so on and so forth. Ofcourse this will only go so far but I think so far this gen this is what is ment by the devs.
